TAPERS: Machinists often turn, plane, bore, and grind tapers on a variety of parts, therefore, it is important to be familiar with the common standard tapers—American National Standard, Brown and Sharpe, Morse, and milling-machine arbor and spindle. How to determine the taper per inch or percentage of taper from a sample piece of work is a common problem. A study of the data and the rules in this section will help you handle taper problems. Taper Calculations: A cylindrical taper is a piece of material that decreases in diameter in a cone shape. Proportions for tapers are often expressed as Taper per Foot (TPF), or Taper per Inch (TPI). Taper calculations are most often expressed in terms of the difference in diameter at the opposite ends of the taper and the length of the taper center axis. Contact me if you would like for me to email the full PDF with all of the taper calculations to you. You may also download the Tapers PDF. Thanks for visiting www. MachinistKalc.com today. The m

Coordinate Constants from Outside: These are used for establishing coordinate hole locations from the outside of a bolt circle with equally spaced holes. The holes can be aligned to a reference point on a centerline or equally spaced on both sides of the centerline. To use these values, first, select the required number of holes for the bolt circle.  Next, choose the appropriate type of coordinate reference location (either on the centerline or between the holes).  Then, multiply the diameter of the bolt circle by the constant value shown in the chart.  The resulting answers represent the coordinate locations of the holes from the "X" and "Y" reference edges for the specified diameter of the bolt circle. The full PDF  can be downloaded and includes coordinate constants for 3 to 12 holes. Contact me if you prefer that I email this to you instead.
